Corporate earnings will continue to slump into the first half of 2009 amid the first simultaneous recessions in the US, Japan and Europe since World War II.

Earnings at Standard & Poor's 500 companies will probably fall in the first half, marking eight straight quarters of declines. In Europe and Asia, the outlook may be even worse as the recession curbs demand for retail goods and exports.

"It's going to be a miserable ride," said Bruce McCain, chief investment strategist at Cleveland-based Key Private Bank, which manages about $30 billion. Earnings probably won't rebound until the end of 2009, he said. "The market recovers, then the economy recovers, then finally the earnings recover."
